can grandia 1 and 2 be played on steam? if so how?

im still new to owning a steam deck and found out that the two grandia games arent support by steam deck. huge bummer because i love jrpg games and wanted to try them after kingdom of the dump.

i heard if i download something and edit the files. i can make grandia work. how do i go about it? i dont wanna brick a 1k console
